Risse is usually identified as a constructivist scholar of international relations. In contrast to American constructivists, his work borrows heavily from German social theory and philosophy, and in particular the work of Jürgen Habermas. His work suggests that communicative action can reshape actors' understanding of their interests with important consequences for world politics. During the 1980s the main focus of his work laid on security policy, his dissertation “Die Krise der Sicherheitspolitik” dealt with foreign and security policy decision making processes in West-Germany. In his thesis he observes the development of a Peace movement and theorised their influence on West-German foreign policy. The contribution of his work is crucial to IR theory because it opposes the logic of equality between force and deterrence. With the end of the Cold War, the focus of his work shifted to transnational relations and human rights. One of his works out of this period is the edited volume “Bringing Transnational Relations Back In”. Here he argues that regular interactions between non-state actors, that do not act on behalf of national governments, but try to influence the policies of a state, got out of focus. These organisations could be various NGOs for example, the Socialist International, Amnesty International or religious groups among others. In this volume an outlook on methodology and theory of transnational relations and their impact on domestic policy is developed. Another work of reference of this period is “Die Macht der Menschenrechte”. Based on liberal theory and democratic peace, Risse looks at international norms, speech acts and political change in the South. Whereby the main focus is laid on the realisation of human rights. His core theory is that the key for respect of human rights is the influence on transnational and domestic civil society on state structures. Inter alia he shows that economic development and democratisation do not forcibly go hand in hand. Post 9/11 his focus changed again towards research on failed states and governance. In his latest publication he focussed on aspects of governance in areas of limited statehood – distinct from failed states.
